# Agent Score Fix Report — Vapi URL: https://docs.vapi.ai/quickstart/introduction Score: 86/100 (Grade B) I need help improving the AI-readiness of the documentation at https://docs.vapi.ai/quickstart/introduction. Agent Score found 5 failing checks and 1 warnings. ## Failing Checks (5) - [content-discoverability] Llms Txt Directive: No llms.txt directive found in any of 10 sampled pages - [page-size] Page Size Markdown: 3 of 9 pages exceed 100K chars (max 948K) - [page-size] Page Size Html: 3 of 10 sampled pages convert to over 100K chars (max 948K, 3% boilerplate) - [page-size] Content Start Position: 1 of 10 sampled pages have content starting past 50% (worst 74%) - [observability] Markdown Content Parity: 4 of 9 pages have substantive content differences between markdown and HTML (avg 20% missing) ## Warnings (1) - [content-discoverability] Llms Txt Valid: llms.txt contains parseable links but doesn't fully follow the proposed structure: https://docs.vapi.ai/quickstart/introduction/llms.txt: No H1 heading found, No blockquote summary found, No markdown links found; https://docs.vapi.ai/llms.txt: No blockquote summary found; https://docs.vapi.ai/docs/llms.txt: No blockquote summary found, No heading-delimited sections found, No markdown links found ## Fix Instructions For each issue above, please: 1. Analyze the documentation site at https://docs.vapi.ai/quickstart/introduction 2. Implement the specific fix 3. Verify the fix would cause the check to pass ### Common fixes: - **No llms.txt**: Create /llms.txt following https://llmstxt.org — list all doc pages in markdown format - **No .md URL support**: Configure your docs platform to serve pages at equivalent .md URLs (e.g. /docs/quickstart.md) - **No content negotiation**: Return markdown when request includes Accept: text/markdown header - **Large page size**: Reduce nav boilerplate, inline scripts, and repetitive markup - **No sitemap**: Generate /sitemap.xml listing all documentation URLs - **Auth walls**: Ensure docs pages return 200 without requiring login cookies or tokens - **No Last-Modified header**: Configure your server/CDN to include Last-Modified response headers - **Tab content hidden**: Ensure tabbed content is rendered in the HTML (not JS-only) so agents can read all variants ## Run afdocs Locally for More Detail To get deeper visibility into what's failing, run afdocs against your docs: npx afdocs https://docs.vapi.ai/quickstart/introduction --fixes --verbose - **--fixes**: Adds "Fix:" lines to the output for each warn/fail check with actionable remediation steps - **-v, --verbose**: Shows per-page details (specific URLs, character counts, error codes) for checks with issues — useful for per-URL visibility into what's failing
